This would definitely be correct. How much impact the master process
has depends on how much it's doing.

Following up to my own post...
Flickr informs me that quite a few of you have been looking at my

Hello again, everyone.
I'm developing some custom neural network code. I'm using Python
2.6, Numpy 1.5, and Ubuntu Linux 10.10. I have an AMD 1090T six-core
CPU. About six weeks ago, I asked some questions about
multiprocessing in Python, and I got some very helpful responses from
you all.
